Ferrotungsten 80txhais tau hais tias cov ntsiab lus tungsten nyob nruab nrab ntawm 75% thiab 85%.
Ferrotungsten yog cov hlau alloy series (tungsten cov ntsiab lus: 70%-80%). Nws yog ib qho alloy uas tsim los ntawm tungsten thiab hlau thiab yog siv los ua cov khoom siv ntxiv rau steelmaking. Feem ntau siv ferrotungsten muaj 70% thiab 80% tungsten. Ferro W yog tsim los ntawm tungsten manganese ore los ntawm kev txo nws nrog carbon nyob rau hauv lub cub hluav taws xob. Feem ntau yog siv los ua cov khoom siv alloying additive rau tungsten-muaj alloy steel (xws li high-speed steel).
